Hastelloy C2000 is engineered for universal corrosion resistance. When standard stainless steel fails, this material provides a definitive solution. Its unique composition is a game-changer. Understanding its properties is vital. It ensures your stainless steel pipes and stainless steel pipe fittings perform flawlessly.
What is Hastelloy C2000 | UNS N06200
Hastelloy C2000 is a nickel-chromium-molybdenum alloy that belongs to the Hastelloy family. This alloy is designed for broad resistance. It handles both oxidizing and reducing acids. A key element is copper , which provides enhanced resistance to sulfuric acid. It represents a significant upgrade.
Key Advantages of Hastelloy C2000
Hastelloy C2000 resists a wide range of aggressive chemicals. It battles oxidizing and reducing environments. This includes strong acids and chlorides. It protects assets in the harshest conditions.
Molybdenum and tungsten create a stable passive layer. This actively resists localized corrosion. This is crucial for flanges and stagnant areas. It prevents unexpected failures.
The alloy has very low carbon content. This prevents sensitization. It maintains corrosion resistance after welding. This is critical for fabricated stainless steel pipe.
The copper addition provides unique resistance. It protects against sulfuric acid environments. This expands its application range. This is a key advantage over other C-grade alloys.
